LOL....what's goin' on buddy.......i find that zonata do just fine in the smaller enclosures such as the 32 quart blanket boxes. By giving them stacks you also increase the usability of available space within their enclosure and can allow for greater choice selections, as well as variability of thermoregulation depending on your arrangement. As a general statement, z habitat isn't "vast" as they are fossorial and utilize smaller niches which provide for the functions they require & engage in. here's an example of what I use which has yielded excellent results:
Animal Plastics rack with 3" FlexWatt set at 85F at the rear:

Damp hides are also important, particulrly for hatchling and juvenile zonata:

Stacks can be made for small and larger z's or pyro's.......simply select the appropriate size tiles. This kind of security is gratly beneficial and allow them to do what comes naturally, which is the best choice for them to feel secure:

I sometimes allow same-sex pairs to occupy one tub as, again, stacks afford more usable space. It works well for me with no negative outcomes. These are two female black & white (axanthic/anery) zonata multicincta:

And even for some adults, like this Santa Clara coastal zonata, I tend to provide an occasional damp box usually during a shed cycle:

And lastly, the occasional stroll in the grass is optimal during spring and fall. Even this St.Helena/Napa zonata zonata would agree.

Best of wishes Tim in all your endeavors!
